practice begun presumably by lesbians. Told to me by one. A "knee ride" is using ones knee to place pressure on a woman's vaginal and clitoral area. By applying pressure and rubbing your knee against this area you can stimulate orgasm.
After my lesbian friend told me about knee rides I gave my girlfriend one. She couldn't believe that I give her an orgasm using just my knee.
